Dawn Operating Normally After Safe Mode Triggered

Elizabeth Landau, NASA's Jet Propulsion Laboratory The Dawn spacecraft has resumed normal ion thrusting after the thrusting unexpectedly stopped and the spacecraft entered safe mode on September 11. That anomaly occurred shortly before a...

NASA Research Helps Response To California Napa Quake
2014-09-11 03:41:30

Alan Buis, NASA's Jet Propulsion Laboratory NASA data and expertise are proving invaluable in California’s ongoing response to the Aug. 24 magnitude 6.0 earthquake in Napa Valley, northeast of San Francisco. The quake was the strongest to occur in the San Francisco Bay Area in a quarter-century and caused significant regional damage. [ Watch the Video: NASA Radar Data Reveals Fault Movement From Napa Quake ] Analyses by scientists at NASA’s Jet Propulsion Laboratory, Pasadena,...

plate tectonics on Europa
2014-09-08 12:06:43

NASA/JPL Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth. Researchers have clear visual evidence of Europa's icy crust expanding. However, they could not find areas where the old crust was destroyed to make room for the new. While examining Europa images taken by NASA's Galileo orbiter in the early 2000s, planetary geologists Simon Kattenhorn, of the...

Mars rover Opportunity
2014-08-30 08:04:54

Guy Webster, NASA Jet Propulsion Laboratory An increasing frequency of computer resets on NASA's Mars Exploration Rover Opportunity has prompted the rover team to make plans to reformat the rover's flash memory. The resets, including a dozen this month, interfere with the rover's planned science activities, even though recovery from each incident is completed within a day or two. Flash memory retains data even when power is off. It is the type used for storing photos and songs on...

New Horizons view of Neptune
2014-08-25 13:01:28

NASA/JPL NASA's Pluto-bound New Horizons spacecraft has traversed the orbit of Neptune. This is its last major crossing en route to becoming the first probe to make a close encounter with distant Pluto on July 14, 2015. The sophisticated piano-sized spacecraft, which launched in January 2006, reached Neptune's orbit -- nearly 2.75 billion miles (4.4. billion kilometers) from Earth -- in a record eight years and eight months. New Horizons' milestone matches precisely the 25th anniversary...

Bonanza King a no-go for NASA
2014-08-23 10:52:28

Guy Webster, Jet Propulsion Laboratory Evaluation of a pale, flat Martian rock as the potential next drilling target for NASA's Curiosity Mars rover determined that the rock was not stable enough for safe drilling. The rock, called "Bonanza King," moved slightly during the mini-drill activity on Wednesday, at an early stage of this test, when the percussion drill impacted the rock a few times to make an indentation. Instead of drilling that or any similar rock nearby, the team has...

california Central Valley drought
2014-08-19 02:30:55

Rosalie Murphy, JPL Earth Science and Technology Directorate About 60 percent of California is experiencing "exceptional drought," the U.S. Drought Monitor's most dire classification. The agency issued the same warning to Texas and the southeastern United States in 2012. California's last two winters have been among the driest since records began in 1879. Without enough water in the soil, seeds can't sprout roots, leaves can't perform photosynthesis, and agriculture can't be sustained....

Cuiosity Rover Eyes Bonanza King
2014-08-17 08:44:42

Guy Webster, Jet Propulsion Laboratory The team operating NASA's Curiosity Mars rover has chosen a rock that looks like a pale paving stone as the mission's fourth drilling target, if it passes engineers' evaluation. They call it "Bonanza King." It is not at the "Pahrump Hills" site the team anticipated the rover might reach by mid-August. Unexpected challenges while driving in sand prompted the mission to reverse course last week after entering a valley where ripples of sand fill...

2014-08-15 05:33:22

Elizabeth Landau, Jet Propulsion Laboratory As a high school student at a study program in Japan, Brian Trease would fold wrappers from fast-food cheeseburgers into cranes. He loved discovering different origami techniques in library books. Today, Trease, a mechanical engineer at NASA's Jet Propulsion Laboratory in Pasadena, California, thinks about how the principles of origami could be used for space-bound devices. "This is a unique crossover of art and culture and technology," he...
